How to Spray

333394F 11

How to SprayTake a few moments prior to spraying and re-view these simple tips to ensure your spray-ing project is a success.

Dual Speed Control(Not available on all units)

The speed control feature allows you to slowdown or speed up when spraying.

• Turn the dual speed control to LOW to slow down the speed of application when first learning to spray or when spraying small items that require more control.

• The LOW setting delivers more control and reduces overspray when spraying thinner materials such as stain.

• Turn the dual speed control to HIGH when you want to get to job done fast and when spraying large surfaces.

• To reduce overspray, always spray at lowest speed that results in an accept-able spray pattern.

Spray TechniquesUse a piece of scrap cardboard to practicethese basic spraying techniques before youbegin spraying the surface.

• Hold sprayer 10 in. (25 cm) from surface and aim straight at surface. Tilting the sprayer to direct the spray angle causes an uneven finish.

• Flex wrist to keep sprayer pointed straight. Fanning sprayer to direct spray at angle causes uneven finish.

NOTE: How fast you move the sprayer will affect spray application. If material is pulsat-ing, you are moving too fast. If material drips, you are moving too slow. See Troubleshoot-ing, page 24.
